This understanding lead to the creation of a plot known as theHertzsprung-Russell (H-R) diagram, a graph of stars based on their brightness and color (which in turn shows their temperature). Most stars lie on a line known as the "main sequence," which runs from the top left (where ho...
A main sequence star is any star that has a hot, dense core which fuses hydrogen into helium to produce energy. Most stars in the galaxy are main sequence stars, including Alpha Centauri A, Tau Ceti and the Sun. Stars are formed by the gravitational collapse of gas and dust from the ...

V.B Evolution on the Main Sequence During the burning of H in their cores, stars move very slowly away from the ZAMS. The main-sequence lifetimes, up to exhaustion of H at the center, are given in Table III. High-mass stars go through this phase in a few million years, while stars...
We have recently obtained clear evidence that asteroseismology of main sequence solar-type stars can give signatures of the chemical variations inside the stars and provide a better understanding of these processes. 展开 会议名称: International Astronomical Union Colloquium ...
All stars die eventually, but the way a star dies varies based on its structure. In this lesson, discover the lower-main-sequence stars, known as red dwarf and medium-mass stars. Additionally, study how convection, mass, and carbon fusion affect their lifespans, and learn how these stars ...

Outbursting Stars, Pre-Main-Sequence Stellar Evolution, Convection, and Lithium BurningThis historical note summarizes some of the key events related to pre-main-sequence evolution, and in particular the importance of convective energy transport, that led to my Ph. D. dissertation in 1965.P. ...
